Subject [jira] [Closed] (LUCENENET-179) SnowballFilter speed improvment
Date Thu, 22 Mar 2012 16:50:22 GMT

     [ https://issues.apache.org/jira/browse/LUCENENET-179?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Christopher Currens closed LUCENENET-179.
-----------------------------------------

    Resolution: Invalid

It's been so long since this patch was submitted (2009), that it's no longer needed.  The
new version of the SnowballFilter from 3.0.3 only uses reflection in the constructor to create
the filter (as does the patch).  It's too bad this didn't make it into 2.9.4, where it could
have really been used.

> I'm using Lucene.Net along with snowball stemming to index text from a database. The
class Lucene.Net.Analysis.Snowball.SnowballFilter uses the reflection API and the invoke method
to call the stem methods of snowball. I have written a Snowball filter which creates a delegate
and uses this delegate to stem the words afterwards. This approach improves the indexing speed
of my indexing program by about 10%. I would be happy if you include this code into lucene.net.
